Abstract

Cette invention concerne un analyseur de liquide organique sur tampon réactif, de l'urine par exemple, comportant un moyen d'éclairage du tampon imbibé de liquide organique, un moyen de détection de la lumière réfléchie par le tampon, un moyen de générer un premier signal de réflectance puis second signal décalé dans le temps et un moyen d'afficher une couleur fonction des amplitudes des deux signaux. Le moyen d'affichage d'une couleur correspondant à l'état de l'échantillon de liquide organique peut faire appel à un moyen de détermination d'une paire de coefficients colorimétriques, la valeur de chacun étant fonction des amplitudes des signaux de réflectance.
